Brassica plant named ‘Kaleidoscope’

ABSTRACT

A new cultivar of hybrid  Brassica , ‘Kaleidoscope’, characterized by its dark purple-green foliage with highly ruffled edges, its magenta pink veins and its margins that are magenta pink in color when grown under cool temperature and lavender in color when grown under warm temperatures such as early season growth.

Botanical classification: Brassica oleracea.

Cultivar designation: ‘Kaleidoscope’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of hybridOrnamental Kale, botanically known as Brassica oleracea ‘Kaleidoscope’and will be referred to hereafter by its cultivar name, ‘Kaleidoscope’.The new cultivar represents a new Ornamental Kale, a plant grown as anannual for fall landscape use as a container and bedding plant.

The Inventor discovered the new cultivar, ‘Kaleidoscope’, in his nurseryin Dahlonega, Ga. in the autumn of 2007. ‘Kaleidoscope’ was discoveredas a single unique plant in a one-gallon container in a block ofcontainers planted with seed of Brassica oleracea ‘Redbor Kale’ (notpatented).

Asexual reproduction of the new cultivar was first accomplished by theInventor using stem cuttings in Dahlonega, Ga., in November of 2007. Thecharacteristics of this cultivar have been determined to be stable andare reproduced true to type by both in-vitro propagation and cuttingproduction in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘Kaleidoscope’ from other varieties of Brassica oleraceaknown to the Inventor.

-   -   1. ‘Kaleidoscope’ exhibits purple-green foliage with highly        ruffled edges.    -   2. The foliage of ‘Kaleidoscope’ is variegated with margins that        are magenta pink in color when grown under cool temperature and        lavender in color when grown in warm temperatures such as early        season growth.    -   3. The foliage of ‘Kaleidoscope’ exhibits veins that are magenta        pink in color.

‘Kaleidoscope’ differs from the parent plant, ‘Redbor’ by havingmarginal variegation that is magenta pink in color. The foliage of‘Redbor’ is solid purple-green in color and lacks the magenta coloredmargins. ‘Kaleidoscope’ has a similar growth habit, ruffled leaf marginsand vein color to ‘Redbor’. ‘Kaleidoscope’ can also be compared to‘Winterbor’ (not patented), ‘Winterbor’ has a similar growth habithowever the foliage of ‘Winterbor’ is medium green in color.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs were taken in September of 11month-old plants of ‘Kaleidoscope’ and illustrate the overall appearanceand distinct characteristics of the new Ornamental Kale.

The photograph in FIG. 1 shows six plants of ‘Kaleidoscope’ as plantedin the landscape with the center foliage characteristic of the foliagewhen grown under cool temperatures.

The photograph in FIG. 2 is a view of a plant of ‘Kaleidoscope’ as grownin a one-gallon container.

The colors in the photograph may differ slightly from the color valuescited in the detailed botanical description, which accurately describethe colors of the new Ornamental Kale.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 6 month-old plants of the newcultivar as grown outdoors in one-gallon containers under natural lightin Dahlonega, Ga. Leaf data was also collected from younger 2 month-oldplants as grown under plastic cover in one-gallon containers at aminimum 40° F. night temperature (cool temperatures) in Dahlonega, Ga.and provide. The phenotype of the new cultivar may vary with variationsin environmental, climatic, and cultural conditions, as it has not beentested under all possible environmental conditions. The colordetermination is in accordance with the 2007 R.H.S. Color Chart of TheRoyal Horticultural Society, London, England, except where general colorterms of ordinary dictionary significance are used.
